The International Centre for Research in Agroforestry (ICRAF) provides
the following definition:
Agroforestry is a collective name for land-use systems and
technologies, where woody perennials (trees, shrubs, palms, bamboos,
etc.) are deliberately used on the same land management unit as
agricultural crops and/or animals, either in some form of spatial
arrangement or temporal sequence. In agroforestry systems there are both
ecological and economical interactions between the different
components'. (ICRAF, 1993)
Recently the following modification was done to incorporate the 'new'
Agroforestry should be reconsidered as a dynamic, ecologically based,
natural resource management system that, through the integration of
trees in farm and rangeland, diversifies and sustains production for
increased social, economic and environmental benefits'. (Leakey, 1996)
Another author (Wyant, 1996) states that for an AFOs to become
successful it must comply with an inherent "ecosystem integrity" which
he defines as follows:
The ecological integrity of an agroforest is a state of system
development in which the habitat structure, natural functions and
species composition of the system are interacting in ways that ensure
its sustainability in the face of changing environmental conditions as
well as both internal and external stresses'.
